Building Instructions for the Predator Gas eCCPM helicopter kits.

Introduction

Congratulations on your purchase of Century Helicopter Product's newest RC helicopter model. The

Predator Gas eCCPM is an excellent addition to Century’s Predator model helicopter line. The two stroke

gasoline Predator is well suited for all flying levels and lowers fuel costs while extending into markets where

the glow engines cannot compete. Compared to other 60 class models, pilots will be elated to find the

Predator Gas is easy to build. This kit will exceed your expectations for precision control at an affordable

price.

In order to take advantage of the Predator’s performance capabilities we recommend using a high quality

computer radio system with 120 degree eCCPM mixing. The radio system should have at least 8 channels

to use modern heading lock gyros and throttle governors. The radio should also have a minimum of 5

programmable points on both throttle and pitch curves. Servos used should be a matched set of 3 for the

collective system, be of quality coreless, ball bearing and having a minimum torque rating of 70 oz/in. The

tail rotor servo should have a servo speed of 0.11sec/60 degrees or better.

Warning

This radio controlled model is not a toy! It is a precision machine requiring proper assembly and setup to

avoid accidents. It is the responsibility of the owner to operate this product in a safe manner as it can inflict

serious injury otherwise. It is recommended that if you are in doubt of your abilities, seek assistance from

experienced radio control modelers and associations. As manufacturer, we assume no liability for the use of

this product.

Pre-assembly Information

Upon opening the kit, all the major component parts are bagged by relationship to the different sections of

the helicopter. Various assemblies have been pre-assembled only requiring the final assembly. The particular

parts, screws and nuts required for each step are packaged in the same bag as the parts. Be careful when

opening each bag as not to lose any hardware. As a reminder, all metal to metal screw assemblies require

L242 Blue thread lock compound, all metal to plastic screw assemblies require slow setting cyanoacrylate

adhesive (Slow CA) and all bearing race to metal shafts should use L262 Red threadlock compound.

Care has been taken in filling and packing of each bag however mistakes do happen, if there is a parts

shortage or missing hardware please contact us at:

Helicopter Building Safety

Upon opening the helicopter kit, various components have been

pre-assembled to allow the builder to progress quickly through

the construction process. Ultimately, it is your responsibility to

check and verify that all components are installed and setup to

operate properly.

This manual has been written for both the Predator Gas, CN1303 & Predator Gas SE, CN1304 series of

helicopter kits. The manual follows a step by step approach to building the helicopter with highlight labeling for compo-

nents that are included in the Gas SE only.

Every attempt has been made to ease the assembly of your kit, at each step where there are complex assemblies you

can read the detailed written instructions to walk you through each step. Remember to take a few minutes before each

step to carefully examine the step in order to become familiar with the parts and assembly sequence before beginning

that step.

The entire rotor head comes pre-assembled with

the standard HI6181A (red) head dampers

installed. 3D and aerobatic pilots should disas-

semble the rotorhead and install the hard

HI6181B (black) head dampers. Press in the

head dampers into the rotor head block. Lubri-

cate the inside surface of each damper with

light oil. Leave the M2.5 screws loose.

M3 Threaded Stud

Bond the M3 threaded stud into the head button using

L262 Red threadlock then apply more threadlock to the

exposed threads and thread into the top of the rotor head

block. Remove any extra threadlock compound.

Insert one ball bearing into each

bearing cup and insert into the offset

plate. Apply one small drop of slow

cyanoacrylate glue (Slow CA) to the

joint between the backside of the

bearing cup and the offset plate.

Insert one ball bearing into each tie

bar, using an available M3 socket

cap screw form threads into both

ends of the tie bars. Insert one M3x6

button head screw through the

right

side hole of the offset plate (see

photo) and thread into one tie bar.

Make two identical sub-assemblies.

Note that the bearing cups face

outwards from the head block. Insert

one M3x15 button head screw

through the tie bar bearing, slide one

steel spacer and carefully apply

L242 Blue threadlock to the exposed

threads and insert into the right side

of the head block. Do not over-

tighten. Repeat for the second sub-

assembly. Once complete apply a

small amout of slow cyanoacrylate

glue and insert one HI6167 special

long thread ball into each offset plate

to complete the assembly.

CNLR1014 short steel ball into the single

hole side of the bell mixer and install the

CNLR1020 medium steel ball using L242

Blue threadlock. Install the medium steel

ball according to the table to suit your

flying preference. Use the center hole for

sport flying. Make two assemblies.

Step 4 Bell Mixer

Press one M8x16 ball bearing into both ends of

each main rotor blade grip. Slide one M14

thrust washer against the bearing closest to the

main rotor blade. Make sure that the bearing

and the thrust washer are properly seated into

the deep end of the blade grip. If necessary use

a socket that matches the outside diameter of

the bearing and press into position. Make two

assemblies.

Remove one damper and press the feathering spindle to seat the ball near the center of the rotor hub. Reposition the

rubber damper in the rotor hub and slide one large shim against the damper followed by three regular stiffness shims and

one blade grip assembly onto the feathering spindle. The bell mixer and pitch arm of the blade grip is mounted on the

leading edge when as the head rotates clockwise. Install the M7x15 thrust bearing and lubricate the bearings with light

grease. Looking at the two steel races of the thrust bearing, note that the innermost surfaces have different widths

because the inside diameters are different. Slide the first larger diameter steel washer (thin race, larger ID) followed by

the greased ball race, followed by the second steel washer (thick race, smaller ID). Remove any grease that may have

transfered to the threads using a cotton swab dipped in alcohol. Apply L242 Blue threadlock to the inside threads on the

feathering spindle using a pin and install the M5x10 socket cap screw with washer. Do not overtighten this bolt because it

will flair the end of the spindle making removal of the blade grip nearly impossible. Repeat for the other blade grip.

for RC cars.

Step 8 Flybar Control Yoke

Pushrod A is already assembled but check that the

length is actually 47mm (center to center). As the

pushrods are build and installed they should be checked

for tightness. Press one ball link onto each double

studded steel ball, making sure that pressure is applied

from the side of the ball link with circle mark. While

holding one flybar control arm, apply a small amount of

slow cyanoacrylate glue and thread one end of the

double studded steel ball into each standoff. When it

becomes difficult to turn with fingers, apply slow CA to

the threads and start screwing in the tapered control

arm stand-off on the other end of the ball.

direction. Look carefully at the hole for the ball,

one side is clean while the other side has a

circular mark, 1mm larger than the hole. The

marked side presses over the steel control balls.

A correctly installed the ball link should rotate with

some resistance when the metal pushrod is rotated in

your fingers. If the ball link to too tight the preferred

solution is to purchase Century’s ball link sizing tool

[CN2055] to custom fit each ball link to its steel ball.

Step 9 Flybar & Flybar Paddles

Slide and center the flybar through the head assembly. Carefully look at the flybar control arm assemblies from the previ-

ous step and notice that when installed correctly,

the securing set screw is on top. Insert one M4x6x0.5 micro washer

#CNLR1006 against each bearing then slide the control arm halves onto each side, so that they match together and the set

screw remains on top. Insert one M3x12 button head socket screw to secure the opposite standoff, hold the tapered

standoff using pliers while tightening the screw (to avoid the double studded ball from stripping the plastic threads in the

center). Loosely tighten the M4x5 set screws into the round aluminum inserts aligned with the flat spots on the flybar.

Using a ruler, check the distance between the end of the flybar and the control arm and adjust until the lengths are the

same. Tighten both set screws, one at a time using L242 Blue threadlock. Make a pencil mark 5mm past the threads on

both ends of the flybar. Thread the flybar paddles onto the flybar until the mark is reached, align the paddles parallel. Again

using the ruler, rotate one paddle or the other to get equal distances, remember leading edge of the paddles turn clockwise.

Set the length of pushrod B to 26mm (center to center) and attach to the ball on the adjustable side of the bell mixer and to

the steel ball on the lower seesaw assembly. Check the ball links for proper fit, adjusting if necessary and remember that

the bell mixer is positioned on the leading edge as the rotor head rotates clockwise.

The cooling fan hub and fan comes assembled but

requires final assembly. Remove each of the M3x6

flat head screws

one at a time, apply L242 Blue

threadlock and tighten back into the cooling fan hub.

If a governor is planned to be installed, install mag-

nets into the holes provided in the bottom of the

cooling fan. A similar hole has been made in the

cooling fan shroud mount plate to mount the sensor

on the right side (muffler side) of the engine.

Step 11 Gas Engine Preparation

Remove and keep the four M4x14 Phillips head

screws to remove the pull start unit from the factory

mount plate. Similarly remove the factory pull start

plate and also keep the M5x14 flat head screws. The

screw will be reused to mount the engine and pull

start unit to the helicopter.

Care must be taken in removing the M5 flat head

screws from the engine because they are very tight.

Use the T-handle Phillips screwdriver tool that is

included with the engine, as this it the correct size.

Step 12 Landing Gear Frame

Align the engine crankcase to the

landing gear frame and carefully route

the red coil wire above the coil without

putting a strain on the wire. Insert

three M5x15 countersunk Phillips

screws using L242 Blue threadlock.

On some helicopters, the clutch will sit

slightly below the bottom of the

clutchbell. If needed, insert three shims

between the engine and the landing

gear frame.

These

only hold the plate while starting, do

not overtighen. Install the M4x10

socket bolts with spacers to the

forwardmost holes using threadlock.

Using the original M4x14 Phillips

bolts, insert the screws through the

removable plate with the larger end of

the keyholes in the counter clockwise

direction. Mate the pull start unit from

the other side with the handle down

and rearward and secure with four

M4 locknuts. This will position the

handle on the carburetor side with

space to pull freely.

Note that the pull start handle should be on the carburetor side.

Align the pull start plate keyholes to the bolts on the bottom plate,

press towards the engine and once the two plates are flush, rotate

the pull starter unit clockwise until it stops. Removal is just the

opposite. When choosing to use the removeable plate, the

starter

unit must be removed prior to flying the model, as it could easily fall

during flight off from vibration.

Step 15 Fixed Pull Start Unit

Look carefully at the bottom plate as there are four

M4 threaded holes to the immediate right edge of

each oval slot. These are to permanently attach the

pull start unit to the bottom plate. Position the pull

start unit to have the handle point rearward when the

handle is mounted on the carburetor side of the

engine. This will allow the handle to be pulled without

interference with the landing struts. Attach using four

M4x14 Phillips machine screws using L242 Blue

threadlock.

Step 16 Cooling Fan Shroud Mount Plate

Lay the cooling fan shroud mount plate onto the

face of the engine with the straight edge to-

wards the cylinder head and the access hole on

the muffler side. Install four M5x8 socket cap

screws to secure the plate using L242 Blue

threadlock. Do not overtighten these bolts as

they thread into the front half of the aluminum

cast engine crankcase. Dip a cloth in rubbing

alcohol and degrease the threads in the end of

the engine crankshaft. Apply liquid oil to the

outside taper of the engine crankshaft, the entire

taper should be coated. Do not get oil into the

internal threads. Use Triflow or equivalent oil.

A greater danger is the potential to generate sufficient RF

(radio) noise to cause radio gitching and in certain circum-

stances will force a PCM reciever into radio lock out,

commonly resulting in a crash.

Overtightening the fan hub in the next step

can cause these screw heads to interfer with

the fan, these can be shortened if necessary.

Step 17 Engine Cooling Fan

Slide the cooling fan assembly onto the engine.

Locate the M6x15 socket cap screw and M6x13

flat washer and thoroughly clean these parts to

remove any oil residue. Install the fan assembly

onto the crankshaft. Slide the washer onto the

M6x15 socket cap screw install through the center

of the fan hub. Using a strap-wrench wrapped

around the outside of the cooling fan, tighten the

M6x15 socket cap screw until hand tight and check

the runout of the fan assembly. Acceptable runout is

0.002”, if more, remove the fan assembly and install

again. Once satisfied, remove the M6x15 socket

cap screw, apply L242 Blue thread lock and secure

in place.

that’s it, do not torque these bolts!

If you plan to install a governor, it is best to fabri-

cate the mount for the sensor at this time, get it

fitted and set the sensor gap before the fan shroud

is installed.

Step 19 Clutch Assembly

Apply light oil to the Torrington bearing in the center of the clutch shoe. Be

sure that no grease contacts the edge of the clutch or it could get transfered

to the clutchbell. Slide the clutch shoe onto the fan hub, press down and install

four M3x6 button head screws using L242 Blue threadlock.

Apply a few drops of

light oil on the

Torrington bearing.

Take the time now to make sure that the clutch shoe is

properly seated on the fan assembly by looking at it from the

side and making sure there is no vertical movement as you

slowly turn over the engine. Experience modelers can dial

indicate the clutch, the acceptable amount of runout is 0.002”

Step 20 Rear & X Frame Assembly

Align the rear X frame with the left side of the

rear lower frame (notice the spark plug access

holes align) for the spark plug wire. Insert one

M3x8 socket cap screw from the outside of the

lower frame, through the lower hole only in the X

frame and secure with an M3 locknut on the

inside. Attach the right side lower frame in

exactly the same way.

Assemble these bolts only to position the frames

at this time, they will be tightened when the upper

frames are installed. Note that the upper hole

remains empty until that time also.

Step 22 Battery Tray

Four M3x20 socket cap screws need to

be installed from the inside and threaded

through the battery tray. After the fuel

tank is installed, there is no access to

hold the head of these bolts. We recom-

mend that these bolts be bonded in

placing using L262 Red threadlock (JB

Weld or Slow Cyanoacrylate glue can be

used as an alternative) to permanently

bond these bolts in place.

The fuel tank isolators are a “U” profile that need to be fitted

to the fuel tank openings on the lower front side frames.

Start at the center of one edge and work the isolator into the

frame, seating the corners. Towards the end, continue

forcing the rubber material until the ends butt against each

other. Note that the frames are different sizes and some

trimming is necessary. Starting from the left side, slide one of

the servo side frames onto the threaded studs on the battery

tray, followed by two M3x10x8 spacers and finally the

Left

(

with smaller fuel tank opening) front lower frame. Secure

using one M3 locknut at the rearmost stud, do not overtighten

as it could loosen the bolt on the battery tray.

with two M3 locknuts on the inside flange of the

vertical frame. Install one M3 locknut on the

rearmost stud at the back of the battery tray, the

front stud remains empty at this time.

As you will notice the fuel tank will float between

the front lower side frames. Install the M3x10x17

fuel tank spacer on the right side frame into the

center hole with one M3x8 socket cap screw using

L242 Blue threadlock.

Step 28 Front Frame Assembly

Slide the front frame assembly over the landing gear frame and insert four M3x8

socket cap screws through the lower frames into the landing gear frame,

do not

use threadlock at this time. Install one M4x10 socket cap screw and M4 flat

washer into the slot in the frame, threaded into the side mounts on the engine

crankcase. Do not used threadlock until after the upper frames are installed.

Do not threadlock the frame

bolts until the upper frames are

installed as it is critical to have

the clutch and clutch bell assem-

bly align perfectly. To accom-

plish the frames can be shifted

within the limits of the fasteners.

Step 29 Clutch Bell & Short Bearing Block

Apply a small amount of L262 Red threadlock to the top edge of the

clutchbell and press in place using a

thin walled automotive socket that puts

pressure only on the inside race of the ball bearing. Pressing from the outside

race will damage the bearing which is not covered by warranty. Finally, re-install the pinion

being careful not to cross the threads using L242 Blue threadlock.

Clutch Bell

Assembly 15T

Pre-Assembled

As the 15T pinion has a larger diameter than the top

surface of the clutchbell, it must be removed before the

clutch bearing is changed or installed. The pinion has a

standard right hand thread, if available use strap-

wrenches, grip the outside of the pinion and the clutch

bell firmly and turn anti-clockwise.

The bearing must be

installed into the bearing block before it is installed onto

the clutchbell. Clean the inside race of the ball bearing

and the surface that where the clutchbell will be

installed.

Step 30 Clutch Shaft & Lower Long

Bearing Block

Clean the top of the pinion gear and the inside surfaces of both

the upper and lower bearings inside the clutch shaft bearing block

using alcohol. Apply a small amount of L262 Red threadlock to

the top edge of the clutch gear where it will contact the bearing.

Press the bearing block in place, firmly seating the bearing against

the top of the pinion gear. Insert two M3x12 socket cap screws

from below to attach the long bearing block to the short block. Do

not use threadlock until the gear mesh has been set.

Install the upper main shaft bearing block with the bearing facing upwards onto the left upper side frame (notice the

countersunk hole) using two M3x8 socket cap screws. Install the clutch bell assembly with bearing blocks using four M3x8

socket cap screws and four M3 flat washers. Install one M3x8 socket cap screw only into the forward most hole in the

lower bearing block and install the 26mm hex spacer in the front of the upper frames, secured using one M3x8 socket cap

screw.

Do not use any threadlock on bearing blocks or frame spacers until the gear mesh is set.

Step 34 Elevator Servo

CCPM (cyclic collective pitch mixing) requires that the three servos that drive

the swashplate be the same model and more importantly the same speed and

torque rating. Digital and analog servos will fly the Predator with ease as long as

the minimum torque rating selected is 70oz/in, rated at 4.8 volts.

Install the four rubber gromments

that are supplied with the servo

onto the servo mounts and insert

the brass eyelets so that the flat

washer side of the eyelet is installed

against the side frame. For the

elevator servo the eyelets are

installed from the top of the servo.

Look at the upper side frame, the remaining right side will have

the slots to install the elevator servo. Having previously installed

the rubber gromments and eyelets (see on the right), install the

elevator servo with its output shaft to the rear from the inside

(

outside has the countersunk hole above the main gear) of the

side frame, and secure using four M2.3x10 Phillips

servo screws and two servo mount tabs. Continue

tightening the screws until tight, then back off

1/4 turn.

Start by installing the elevator bell crank

assembly,

note that the left side ball

bearing is flush with the pivot axle. On

the right side frame, the axle extends

outward from the frame to attach the

elevator arm. Install four M3x8 socket

cap screws into the upper main shaft

bearing block, front hex spacer and

forewardmost lower bearing block.

Install four M3x8 socket cap screws into

the clutchbell blocks with M3 flat

washers.

Do not use any threadlock at

this time, these need to be loose until the

main shaft is installed and after the gear

mesh has been set.

Starting on the right side, insert one M3x30 socket cap screw through the right bellcrank (look at the left photo carefully)

on the side with the molded elevator plastic arm. Slide one stepped spacer with the step towards the ball bearing and

position the 26mm threaded spacer between the upper side frames in the rearmost hole (120

CCPM setup) and secure

the right bellcrank assembly. Assemble the left side bellcrank in the same way,

do not apply the threadlock until after the

gear mesh has been set and tighten into the left side of the upper frames.

Right Side

Bellcrank

The technique to remove the two M3x30 socket cap

screws without damaging the 26mm spacer is to

slowly loosen each screw 1/8 turn at a time, chang-

ing from side to side to evenly unload the threaded

spacer. If you notice one side spinning the spacer,

tighten the opposite side again and repeat.

(No threadlock!)

Step 37 Rear CCPM Arm

Align and press the rear ccpm

arm onto the exposed axle with

the arm pointing to the bottom of

the upper side frames. This is a

tight fit, light tapping with a plastic

hammer will help here. Once the

arm is seated, install the M3x10

button head screw to secure it in

place.

The constant drive autorotation unit simply slides apart, pull the inner hub assembly up and out from the outer hub. Install

the inner tail gear by aligning the four countersunk holes in the top of the inner gear with the auto hub inserted from below

using four M3x6 flat head screws and L242 Blue threadlock. Tighten the bolts in numbered order. Assemble the main gear

in the same fashion with the main gear installed on top of the autohub, notice there is an alignment groove. Gas SE kits use

an M15x18x0.20 shim between the inner and outer hubs.

Step 40 Main Gear Pin

Before the main gear assembly can be installed this spacer must be positioned

in the recess of the lower bearing block assembly, it will simply self align in the

block. Slide the main shaft through the upper bearing block, the constant drive main gear assembly, the spacer and finally

through the lower bearing block assembly. Look carefully through the two open M4 threaded holes in the top hub and align

with the hole in the main shaft. Insert and press the M3x15 steel pin through the hub and roughly center it in the main

shaft. Using a permanent marker, mark both holes that will lock the pin in place. Insert the M4x4 set screws in each side

and tighten them equally, using L242 Blue threadlock. These do not need to be torqued down.

Step 41 Bottom Collar

Inspect the bottom collar, make sure that the reduced

step diameter is towards the ball bearing. Slide the

bottom collar against the bearing and insert two M3x6

flat head cap screws using L242 Blue threadlock.

Step 45 Starting Shaft and Hex Coupler

The gas kits include the regular starting shaft and hex coupler as in all the Predator kits to align the clutch to the clutchbell.

Clean both the starting shaft and the inside race of the bearing inside the clutchbell and the inside race of the top starting

shaft bearing. Apply a small amount of L262 Red threadlock positioned just above where the bottom clutchbell bearing will

sit on the starting shaft. Slide the starting shaft up through the bearing

blocks. Apply a small amount of L242 Blue threadlock to the top of

the starting shaft and slide the hex coupler in place aligning

the flat spot with one of the holes. Apply L242 Blue

threadlock to the the two M4x4 set screws and tighten in

place.

#HW6002 Hex

Coupler & M4x4 Set

#HW6005

Starting Shaft

The hex starting system has been successfully used with

the Z231H engine but significant wear on the hex coupler

is common. Regular replacement of the hex coupler is

normal and is not covered by warranty. The pull start

should be used for the first start of the day. Afterwards

using a heavy duty electric starter is possible.

The hex starting is not recommended for the

Z260H engine as damage can occur to your

starting equipment and helicopter components.

If not already

done, remove

and apply L242

Blue threadlock

in place.

Step 46 Main Gear & Clutchbell Gear Mesh

M3x12 Socket

Cap Screws x 2

Loosen the eight M3x8 socket cap screws

that hold the clutchbell assembly and the

two M3x12 socket cap screws between

the upper and lower bearing block assem-

blies. Cut a strip of regular copy paper

12mm x 50mm and thread between the

main gear and the clutchbell gear. Press

the clutch bell towards the main gear and

tighten up the eight bolts. Proper gear

mesh is achieved when the paper strip will

pass between the gears without ripping or

damaging the paper strip, but no looser.

Step 48 Clutch & Clutchbell Alignment

Over the next few steps the upper and lower frames

will be joined. The frames have the necessary slots to

allow for precise alignment between the clutch and the

clutchbell. The goal is to have the clutch sit parallel and

centered in the clutchbell. It is best to sight the bottom

edge of the clutch with the aluminum clutchbell in both

fore-aft and left-right directions to ensure remains

parallel when all the fasteners have been tightened. It

may be necessary to further loosen the frame fasten-

ers.

Parallel

Rear frame

spacers are

stacked.

Now that the gear mesh has been set, go back and remove all

the upper frame screws one screw at a time, apply L242 Blue

threadlock and tighten in place. These include the M3x8

frame screws, M3x30 bellcrank screws and the front hex

spacer screws.
